What does this mark, huawei p30 lite, mean?

Wonder what exactly that sign is. It's actually clear to me that something is being downloaded, but downloading an app is a different sign and downloading is a different one. System update also looks different. It's a bit strange, but can't find anything else on the internet. I can google notification symbols but they all look different like that. 🤷🏼♀️

Do you have an app or a browser that can also be used to download something?

I have a Twitter video download app on my smartphone that leaves a similar symbol in the status bar after a download.

It's not from my cell phone. He sent me a screenshot of my friend and I wonder what he should have downloaded

Do not know that he has anything except playstore, googel and googel chrome
